As a business owner, you probably have a solid attachment to your cell phone and are concerned about the possible radiation hazards associated with cell phone use. As of 2013, this remains a controversial issue, with no apparent links between health problems and cell phone radiation. However, to be safe, wearing wired headphones substantially reduces any radiation you may receive.

Cell Phones and Radiation

Radiation is simply energy produced by an object; a grilled steak emits infrared radiation from its heat, for example. Mobile phones have radiation from the radio waves they transmit. Scientists distinguish radio waves, infrared and visible light from the most harmful radiation, such as X-rays and alpha particles; the latter has much more energy and rapidly damage living tissues.

Radio waves do not produce toxic effects in the short term; they can cause damage after several years of exposure, but evidence has not yet shown a clear connection between the use of cells and cancer.

Headphones with cable and radiation

A wired headset is a headphone-microphone device that fits your ear and connects to your phone via a wired cable. These produce radiation, just like any wire that carries an electrical current.

However, radiation from a corded headset results in weak radio waves at audio frequencies, difficult to detect, even with sensitive equipment, and several orders of magnitude more vulnerable than the radio signal produced by the cell phone. Using a wired headset is one of the safest solutions available to cell phone users.

Best practices

You receive the most substantial radiation dose from a cell phone when you hold it to your ear because it is close to your body; distance reduces any radiation hazard. With a headset, you can place the phone on your desk or the car console, moving it away from your body to significantly decrease your exposure. A wired headset contributes very little of its radiation. You can achieve a similar reduction by using the speakerphone function of your cell phone.

Ferrite core

To reduce the radiation output of a corded headphone as much as possible, select one with a ferrite bead wrapped around the end. You can also purchase a separate ferrite bead accessory specially designed to reduce radiation from headphone cables.

The pearl, made of iron and ceramic, absorbs radio waves. Electronic technicians use them to prevent power, video, and other cables from producing radio interference.
